Gas price in receipt changed from 1.5 > 2.0 #83
Description
Gas price on 1.5 and earlier was the gas price charged on-chain which may be less than the gas price that was in the signed transaction.
2.0 and newer this is the gas price that was signed for in the transaction, which resolves issues that some clients have had (i.e. go-ethereum) where they want to read the transaction and reconstruct their own hash which would not match on 1.5, now with 2.0 as the RPC transaction response includes the price that was signed in the original transaction the hashes match.
We should consider putting the gas price charged on-chain as the effectiveGasPrice, as a means to provide more accurate response data. Currently gasPrice and effectiveGasPrice are both the same value in the RPC response.
